If we knew what "it" was, maybe we could help you. True, the 39A, one of the classiest .22 rifles you can possibly buy, is made to take down into two sub-assemblies. Don't know if "it" does or not. Try again with a more specific question. I have followed the take down instructions in order to take the action apart in two sections, however there is something that has come apart in the interior preventing me from coming up with two pieces when I take the (thumb Screw) out, as it's called step 1 unload the rifle step 2 be sure you have unloaded the rifle step 3 bring the hammer to full cock step 4 lossen the takedown screw step 5 if the gun is fairly new or has never been taken down the rifle due to tight tolerance on these guns, might need a firm slap (with your palm) on the opposite side of the stock from takedown screw in order to get the halves to seperate. just be sure to protect the finish and dont beat it with a hammer step 6 hammer must be cocked for reasembly almost all of them are tight on initial disasembly - Note: do not touch the lever during dissembly and reassembly. Manual shows a picture of tapping barrel muzzle on padded surface. Picture is not clear, but you can also lay gun on your lap with the receiver flat, muzzle to your left, buttstock to your right, with the lever facing away from you - smack the receiver near the half moon shape joint. That is where the two halves dovetail together. At this point the buttstock piece should be able to pivot/lift off the barrel portion of the assembly. If you try the method listed in the manual make sure you are holding the gun "sideways" - so the the receiver is parallel to the floor. Gun should "fold" down in the center to disassemble. The only part that can come out is the bolt/firing pin assembly. It is pretty easy to put back in, study the parts and slide it back into the receiver from the rear prior to assembly. There are parts diagrams on the internet to show orientation of the parts if you aren't sure.
don't take down a Winchester model 52, the way they bedded the rifle was a mystery. It may never shoot the same if you take it apart.

GREAT rifle and easy to break down for cleaning, Best thing to do is unload it first then look at the owners manual as it gives a complete part break down
